This invention relates to apparatus used for carrying out di'erent operations in the wet treatment of hanks of thread, yarn,.silk or other materials. In such apparatus, the

hanks of material are mounted on rods extending crosswise below a tank containing a suitable liquid for bleaching, dyeing or other treatment of the material which is allowed to drip or spray on the hanks. A second tank below the hanks and cross rods serves to collect surplus liquid. Means is provided for advancing the rods between the tanks step by step from one end ofthe tanks to the other. It is also desirable to rotate the rods in their successive positions, so that all parts of each hank will receive uniform spraying and treatment.

It is the general object of my invention to provide improved actuating mechanism for thus intermittently advancing and rotating the rods. l

My improved mechanism is simple in construction and reliable in operation and is particularly designed to prevent entrance of liquid to the actuating mechanism.

My invention further relates to arrangements and combinations of parts which will be hereinafter Vdescribed and more particularly pointed out in the appended claims.

A preferred form of the invention is shown in the drawings, in which F ig. 1 is a sectional end elevation of my improved apparatus; and

Fig. 2 is al partial side elevation thereof on an enlarged scale and looking in the direction of the arrow 2 in Fig. 1.

Referring to the drawings, I have shown the hanks I-I mounted on rods 10 extending crosswise below a tank X adapted to contain any desired liquid for the treatment of the hanks. A second tank Y is positioned below the hanks to receive drippings or surplus liquid. The ends of the rods 10 are normally supported on the peripheral surfaces of adjacent rolls 14.

Each roll 14 is mounted on a sleeve 16 (Fig. l) rotatable in a. fixed bearing 17 formed in one side wall of a casing 18. A worm gear 2O is mounted at the inner end of the sleeve 16 and is engaged by a worm 21 on -tends into a recess 47 formed in a driving shaft 22extending 'lengthwise of the casing 18 and supported in suitable bearings 24 within said casing.

So long as the rods 10 are supported on andbetween the rolls 14, they are continuously rotated and presentfresh portions of the hanks to be sprayed by the liquid contained in the tank X. f Y

f In order to give the rods an intermittent advance movement in a direction lengthwise of the tank X, I provide lifter blocks 30, loosely mounted on crankpins or studs 31 secured in the ends ofcrankarms 32. The arms 32 are mounted on cross vshafts 33 rotatableV within the sleeves 16 lpreviously described. v Y. 'Ihe rear ends of the shafts 33 are also supported in bearings 40 on the outer side wall 'of the c asing 18; A worm gear 41 is mounted on each cross shaft 33 and is engaged by'a worm 42 on' a driving shaft 43`extending lengthwise ofthe casing 418 and also supported for rotation' in the bearing'blocks 24 previously described. p Y

The lifter blocks 30 are concavely recessed `-7-5 at their upper ends to lit underthe rods 10 and to securely supportl the rods as they are advanced to their next forward position. Each lifter block 30 has a downwardly extending portion provided with a vstud 46 which exa depending portion of a link 48. One of these links 48 is yprovided for each adjacentpair-oflifler blocks 30 and 'acts tov maintain the blocks in parallel vertical relation as they are given an orbital movement ythe crankpins or studs As the lifter blocks move upward, they engage under the associated rods 10 and advance the .rods through the successive positions indicated at the right inFig. 2 to a vposition of engagement with kthe next" forward pair of rotating rolls14.

A collar 50 (Fig. 1) Vis mounted oneach cross shaft 33 and holds the associated crank arms 32 snugly-against the outertend of the sleeve'16. A tightly fitting cover 52 extends lengthwise of the casing 18. With this construction the possibility of leakage 4of/liquid from the'rods 10 tothe actuatingmecha- 100 cross shaft These bearings maybe made very close fitting and-'may'beeasily and suitably packed to prevent access 'of liquid thereto. y o

Furthermore, the' only'V entrance ofA movingiV parts'to the' casing' 1'8 is at the side, and the top of the casing may be made continuous and very tight itting This' provision" of effective means to prevent entrance ,of l-.iqiuidy to the driving mechanism is very important in thisf class of appa\r=atus-asthev liquid in the tank X often of an acid` or corrosive nature. v
